Question
Carbon monoxide enhances the Bohr effect. This means that CO will cause a more pronounced shift of the hemoglobin oxygen saturation curve to the left or right? In Ivan" blood, the partial pressure of CO in the blood is far lower than the partial pressure of O_2, yet the percent saturation of hemoglobin by each gas is equal. This result indicates that the affinity of hemoglobin for CO is approximately 238 times greater than O_2? If the partial pressure of O_2 in the body tissues is 20 mm Hg, what is the best estimate of the amount of O_2 (ml/100ml) that can be released from Ivan' blood as it circulates in his systemic capillaries? A.Explanation / Answer
1. If the partial pressure of oxygen in the body tssues is 20 mmHg, Then the amount of oxygen that can be released from Ivan's blood as it circulates in his systemic capillaries will be equal to 10ml/100ml.
Answer : e) 10 ml/100ml
2. Ivan's disorder would not be accompanied by chemoreceptor mediated hyperventillation because the partial pressure of oxygen in his blood is normal.
Answer: d) No, since the partial pressure of oxygen is his blood is normal.
3. Ivan's condition is a problem of transport of gases in the alveolar capillaries and capillary beds in other tissues.
Answer: c) transport of gases between capillary beds and alveolar capillaries in other tissues.
4. With regard to physiology of external respiration, Ivan's condition is most similar to barbituarate poisoning.
Answer: a) barbituarate posoning.
5. Alkalization of the blood ( increase in pH) is not an appropriate component of the aggresive treatment plan for Ivan's disorder.
Answer: b) alkalization of the blood( increase in pH).
